Alexis earns 2 1/2 as much as Gary in a day. James earns $18 more than gallery in a day. If the total salary of all three people is $306 find Alexis's salary.

20y5 times 2 is 1010 times -2 is -20, plus y

The answer is something i don’t know

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
